Price Hunter
Find the best price for any product across multiple e-commerce platforms.
Quick Start
Input: Product name, model number, or product URL
Output: Structured price comparison table with:
- Platform name
- Price (normalized to user's currency)
- Seller rating (when available)
- Shipping cost estimate
- Direct link
Workflow
Step 1: Clarify the Product
Before searching, confirm:
- Exact product name/model (e.g., "Sony WH-1000XM5" not just "Sony headphones")
- Preferred currency (default: USD)
- Region preference (default: global)
- Any specific requirements (new/used, prime shipping, etc.)
If the user provides a URL, extract the product identity first.
Step 2: Multi-Platform Search
Search these platforms based on relevance:
International:
- Amazon (amazon.com, regional sites)
- eBay
- AliExpress
- Temu
- Walmart
China:
- JD.com (京东) - 京东自营价格较准
- Taobao (淘宝) - 搜索
"{商品名}" site:taobao.com 价格 - Tmall (天猫) - 官方旗舰店,搜索
"{商品名}" site:tmall.com - Pinduoduo (拼多多) - 搜索
"{商品名}" 拼多多 价格或百亿补贴
Platform notes:
- 拼多多:
- ⚠️ 无法提供直接商品链接(网页版需登录,搜索引擎无法抓取)
- 价格来源:第三方聚合站(值值值、什么值得买等)
- 输出格式:提供价格 + 建议用户在拼多多APP内搜索
- 示例:
拼多多 - ¥329 - *请在APP内搜索"Keychron K3 Pro"*
- 淘宝/天猫: 部分页面需要登录,优先用搜索结果的摘要信息
- 京东: 价格相对透明,容易抓取
Region-specific (ask if needed):
- Rakuten (Japan)
- Coupang (Korea)
- Shopee (Southeast Asia)
Use web_search with queries like:
"{product name}" price Amazon"{product name}" site:ebay.com"{商品名}" 京东 价格"{商品名}" 拼多多 百亿补贴
Step 3: Extract Price Data
For each promising result:
- Use
web_fetchto get the product page - Extract: price, seller, rating, shipping info
- Note any coupons or discounts mentioned
Price extraction tips:
- Look for
¥,$,€,£symbols - Check for "from" prices (indicates multiple variants)
- Note if price includes tax/shipping
Step 4: Normalize and Compare
IMPORTANT: Output format depends on platform:
For Discord/WhatsApp (no tables): Use bullet list with inline links:
**🏆 最划算**
• **Amazon** - $279 - Amazon官方 - 4.8★ - [购买](https://amazon.com/...)
• **eBay** - $265 - topSeller99 - 4.9★ - [购买](https://ebay.com/...)
• **AliExpress** - $198 - Official Store - 4.7★ - [购买](https://aliexpress.com/...)
For other platforms (support tables):
| Platform | Price | Seller | Rating | Shipping | Link |
|---|---|---|---|---|---|
| Amazon | $279 | Amazon | 4.8★ | Free | 购买 |
Link requirements:
- Every result MUST include a direct clickable link when available
- Use markdown format:
[购买](URL)or[Buy](URL) - Exceptions:
